I realize that it is not in any of the documents, at least not that I can find:
For running external items off of the GPIO's 5V power what is the maximum safe draw (10A power supply) for the various models of the Raspberry Pi?
I would assume that at least on the 3B and 2B it would be safe to draw 1A at 5V, though I would like to have some verification. And I have no clue for the original model A/B or the A+/B+ or Zero.
For a few projects to reduce the amount of power source wiring I would like to power some things off of the RPi, mostly 28BYJ-48 5v steppers, small servos, and Parallax Propeller P8X32As. Though rather than smoke testing an RPi for this I would like some numbers. Note that for the steppers and servos I am using ULN2803's for the drivers.
Thank you very much.
